EPA Makes Findings of Failure to Lead Nonattainment State Implementation Plans (SIPs) - 2008 Lead Standard
February 7, 2014 - EPA issued findings that 3 areas in the Commonwealth of Pennsylvania missed Clean Air Act deadlines for submitting attainment plans for implementing EPA's 2008 national air quality standards for lead.

Detailed implementation guidance on many topics is provided in the 2008 Lead Standard (PDF)(99pp, 665k) final rulemaking notice. Implementation topics addressed in the 2008 Lead Standard notice include: designations, nonattainment boundaries, Infrastructure, attainment dates, RACM/RACT, attainment demonstrations, RFP, contingency measures, new source review, emissions inventories, modeling, general conformity, and transition policy. In that notice, EPA states that the regulations and guidance currently being used to implement the pre-existing lead NAAQS are still appropriate to implement the revised lead NAAQS with modifications in some cases. The regulations and guidance which address the implementation of the pre-existing NAAQS for lead are mainly provided in the following documents:

‘‘State Implementation Plans; General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990’’, 57 FR 13549, April 16, 1992,

‘‘State Implementation Plans for Lead Nonattainment Areas; Addendum to the General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990’’, 58 FR 67748, December 22, 1993, and

Final Lead Ambient Air Monitoring Requirements
December 14, 2010 - EPA made final revisions to the ambient monitoring requirements for measuring lead in the air. These amendments expand the nation's lead monitoring network to better assess compliance with the 2008 National Ambient Air Quality Standards for lead.

Final Revisions to National Air Quality Standards for Lead
November 12, 2008 - EPA has substantially strengthened the national ambient air quality standards for lead. The revised standards will improve health protection for at-risk groups, especially children.

EPA completes Socio-Demographic Analysis as part of the Lead Air Quality Standards Review
May 20, 2008 - EPA has conducted a limited screening-level analysis of the socio-demographic characteristics of populations living near ambient air lead monitors and stationary sources of lead emissions. EPA completed the analysis consistent with Executive Order 12898, Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations.
